For a 2000 L pond, I would want 4000 LPH coming out the falls. The size pump you will need will depend on how far away and how high the blade is from the pump. Figure that out and then look at the pump curve for any pump you're evaluating. You want to see that it will produce 4,000 LPH in the middle 2/3 of the curve.

Blade size doesn't really matter. More about the look you want. Narrow will produce fast, thick flow. Wide will produce slow, thin flow. I would err on the side of too big and then choke it down if I decided it was too wide.
